What is the terrain actually like?

It is an out-and-back course on the C&O Canal towpath. Expect light gravel and dirt paths rather than asphalt. It is "very runnable," meaning you won't be dodging tree roots or technical rock gardens, but it isn't a road race. The lack of elevation is its biggest selling point; if you want to practice holding a specific split without the interruption of climbs, this is your playground.

Should I prepare for extreme heat?

Yes. You are running in Washington, D.C., in early July. Expect high humidity and temperatures that will climb rapidly after the 6:30 AM start. The National Park Service monitors heat closely, so there is a real possibility of delays or modifications if the index hits unsafe levels. Don't attempt this without a serious hydration strategy; even though there are seven water stations for the half marathon, the "feels like" temperature will be your real opponent.

What are my distance and timing options?

The Half Marathon starts at 6:30 AM, while the 5K follows at 7:00 AM. If you are a slower runner, the organizers are surprisingly accommodating—you can email them to request an earlier start time to beat the midday heat. The half marathon has a 3 hour 15 minute time limit, and there is a designated "back of the pack" pacing category at 12:00 min/mile.

How much am I going to pay?

The pricing is tiered and rewards early birds. For the Half Marathon, you're looking at roughly $77 if you book by mid-June, rising to $87 if you wait until race week. The 5K is even more budget-friendly, starting under $40. Given the course and the charity beneficiary, the pricing feels fair, though you'll want to register before June 24 to guarantee a race shirt.

What can I expect at the finish line?

You'll get the standard glory of an out-and-back completion. They award the top three overall male and female finishers, plus age group awards (1st and 2nd place) for runners ranging from under 19 to over 70. If you're looking for live splits to see how your pacing held up, check Athlinks ↗.
